The annual Mad Hatter's Derby Tea Party is Bangalow Public School's biggest fundraiser and is run to coincide with the crowds at the Billy Cart Derby.

Funds raised this year will go towards purchasing a class set of iPads and Dell tablets, an interactive white board, sports equipment and classroom resources as well as an Aboriginal art project and environmental education program.

Bangalow Public School principal Susie Boyle said she had high hopes for the fundraising event again this year.

"It's our major fund-raiser for the year and for us it provides all of our equipment and materials for our 21st century learning," she said.

"It's also a haven for all the kids to come to when they're not on their billy carts.

"I think it's one of the few billy cart races that still exists.

"It's good old-fashioned fun for the kids and that's why they're so excited to make the billy carts and take part in the billy cart races."

Bangalow Public school student Riley Milsom is a seasoned billy cart driver.

"Sometimes when you're looking down at the hill you feel like backing out but not anymore," he said.

Riley said his cart, which was built six years ago, has already won about five times.

This year will be fellow student Georgia Sproul's second year racing after taking home first place in last year's school race.
